7,861 ios interview questions shared by candidates

When the online debugging test starts, you need to download a project from a private github repo. The project is very big. Certain sections of the code are marked with "DO NOT MODIFY". They give three different tasks to perform in this repo. Task 1: There are a list page and detail page. Find some UI bugs and fix them. You need to be familiar with SwiftUI state management (Observable, State, etc) and MVVM. Task 2: you are expected to create three different ways to concurrently fetch some data using an existing API. The three ways are: GCD (dispatch group), Combine (publisher), and Swift Concurrency (async await). Task 3: You are supposed to debug a login issue. The login always fails or fails some of the time. It's likely a race conditioning issue. The SessionService they provided for authentication verification is completely incomprehensible to me. I have no idea how it works. You are not allowed to use AI coding assistant. You are allowed to look stuff up in a browser but not on stackoverflow.
